It’s cruelty that gets to me. Still, it’s important to read about cruelty.“Why is it important?” Because when you read about it, it’s easier to recognize. That was always the hardest thing in the refugee camps—to hear the stories of the people who had been raped or mutilated or forced to watch a parent or a sister or a child be raped or killed. It’s very hard to come face-to-face with such cruelty. But people can be cruel in lots of ways, some very subtle. I think that’s why we all need to read about it. I think that’s one of the amazing things about Tennessee Williams’s plays. He was so attuned to cruelty—the way Stanley treats Blanche in A Streetcar Named Desire. It starts with asides and looks and put-downs. There are so many great examples from Shakespeare—when Goneril torments King Lear or the way Iago speaks to Othello. And what I love about Dickens is the way he presents all types of cruelty. You need to learn to recognize these things right from the start. Evil almost always starts with small cruelties.
